Paul Farbrace, England's assistant coach, believes there are now more than 20 players who could be selected at any time in the one-day side and still give England a winning combination.

England secured the one-day series against Sri Lanka with a barnstorming chase at The Oval on Wednesday led by Jason Roy's 162 off 118.

They have used 12 players in the four matches.

England are building towards the next two 50-over global events which will be staged on home soil - the 2017 Champions Trophy and 2019 World Cup - but Farbrace says that further advancements are needed to make England credible contenders, especially for the 2019 event.
